Tearing apart hemi 5.7, machine work worth it?

Maybe I should quit trying to modernize the car, stick w a nice carb v8.
I do still want manual tranny, decent electronics, remote start.

I have an 09' charger, do I really want a 73' that drives the same?
These cars were fine how they were made, we like them for the nostalgia...

Plus, carb would be cheaper.
"warmed up 360". U may be right
